Multichoice has shared details with Digicall who keep calling without accurate details of who they should be calling and are telling me that I qualify for a subscription waiver

Multichoice has shared details with Digicall who keep calling without accurate details of who they should be calling and are telling me that I qualify for a subscription waiver. However they expect me to pay a premium every month and provide a name of a person that is over 18 years of age. This makes no sense and sounds like a ****. It seems Multichoice is also in contravention of the POPI Act by sharing subscriber details with *****sters.
